I originally posted this in the Chicken Behavior and Egglaying thread but the conditions have worsened and I believe my girl is really sick. Here is a history. I have a 14 month old White Rock (Dottie) that in the past 4 weeks has started laying soft shell eggs in the middle of the night. This started just as spring start to set on. She did occasionally lay a normal egg during the day but more typically I have found a broken soft shelled egg under were she roosts at night. she has always been a good layer even laid well during the very harsh winter we just had and now that spring is setting on it is as if her system is off cycle. I am still much of a newby when it comes to chickens and learning more very day. I am not experiencing problems with any of the other 5 hens I have. They are on a healthy layer diet and I always have oyster shell available in a separate bowl. They also get a good amount of time to free range my backyard. Other than laying soft shelled eggs in the middle of the night from her roost she appears to be completely normal and healthy. That was my original post summary Today's Update This has been a month now with soft shell or no shell eggs getting dropped out in the middle of the night. The vet I go to for my dogs does have a Avian vet on hand and I did speak with her last we at the time she suggested a few supplements (vitamin D3 and extra calcium) which has provided no help. As a disclosure although she is a Avian licensed vet she is more specialized in exotic birds, not allot of backyard chickens around here. I know she has a network she reaches out to if needed. So this is why I am asking this community of experts your opinion and thoughts so when I call her again I have some things to mention to her from a group that has been raising chickens for a very long time. Ok here is the update. 3 nights ago she continued to lay in the middle of the night from here roost but there has just been the white of the egg, no yoke, no shell, just the egg white on the ground under her. Besides the egg issue she has seemed fine and normal running around with the others, eating and drinking until yesterday. She was fine in the morning when I opened the run to let them out into the backyard for the day, then late afternoon I notice her a bit lethargic laying under a tree. I went out to check on her and she did get up and start to move around digging at the ground, then 15 minutes later I found her laying down behind a storage box. She appeared weak. Not knowing what I am completely dealing with I immediately set up a dog kennel in the garage and isolated her from the others. She has been eating and drinking in there and getting up on the roost I put in the kennel for her but still seems to have no real energy. I am pretty certain this is now a reproductive issue with her. This is where I need input from this community to know when I call in the morning what to ask the vet to check, is there a direction I can guide her to look, is there a blood test or any test that can steer us to the problem. I have been doing some reading and looking up dropping references from What's the Scoop on Chicken Poop. I am fearing she either has ovarian cancer or egg yolk peritonitis. Her poop is very watery and green with white stuff in it. Pictures attached.
